Learning how to build a speaker box allows you to customize the fit and design of the box to match your desired audio quality. The basic two-speaker box designs are sealed and vented. This article details how to build a sealed speaker box, which separates the front and rear sound waves to improve the bass.

Steps

1

Determine the size of the speaker box.

Reference the speaker’s template to find the speaker’s measurements.

The template is included with the rest of the basic speaker information upon purchase. If the template can’t be found, contact the manufacturer for the information or measure the speaker yourself:

Figure the depth (front-to-back dimension) of the speaker box by adding 2 inches (5 cm) to the depth of the speaker.

Use the speaker’s height and length measurements as the box’s internal height and length dimensions.

Multiply the depth, height and length to determine the internal volume of the box.

Adjust the measurements as needed until you reach the recommended range.

3

Add the thickness of the wood to your dimensions to figure the box’s external dimensions.

4

Measure the height, width and depth of the space available for the speaker box to be sure the box will fit.

Use your measurements to sketch out the speaker box depending on the space you need to fit it into.

5

Construct the speaker box.

Trace a pattern onto the MDF (medium density fiberboard) using the exterior box.

Include the circular openings needed for the face of the speaker and the connectors. The measurements are found on the speaker’s template. If there is no template, trace the circumference of the face of the speaker on the front piece and a 2-inch (5-cm) hole on each side piece for the connectors.

This method would work -- you just need to adjust the measurements to fit a 15" driver. It's probably easier to look up a guide designed specifically for a sub though.There are loads of them on car audio sites.

I own a set of Bose 901 speakers that have drivers protruding from the back of the speakers. I need new boxes for these speakers. Are there specialized building methods to incorporate into the new boxes of these speakers? I've contacted Bose, but received no reply.

Yes, they have special design and construction. You won't be able to replicate it on your own.

No. If you connect two speakers in parallel, you will have an equivalent of one 1000 w speaker at 4 ohms. If you connect them in series, you will have an equivalent of one 1000 w speaker at 16 ohms. In doing that, you will either reduce or damage the amp performance.

Yes, but it's often easier to put a portable speaker in a bucket or box to give it some oomph. A box like this is really only for a 'normal' speaker. If you are planning on disassembling the Bluetooth speaker and mount the actual driver, then yes, this should work.
